11d: adj uucits, 'vvhich ect of 1 my aforesaid a. patent.

The main object of ,the nieuts, which I 'shall now-proceed to set forth in deta ihis to remedy certain defects that ex- "ist'ed in my previous perience has shown brick-machines. First. The first-of; the

"reams" toja modification,,, of the meansdPscfri-hed in my Patent No. 207,3&3, of August 27, 1878, of fitting the whereby-such fitting is facilitated;

.9 Those on shaft, so that when the said plate is applied to the latter its lugs will enter the indentations in the shaft until the face of the offset b in the front of the socket of the plate bears against the shoulder 11. The extreme end of theshaft should not touch the bottom of the socket, so that the only hearing-surfaces shall be those of the shoulder and the offset. By this con A struction the thrust-plate b is not only obliged to rotate'with the shaft, but the'fitting of the former to the latter, in order toinsure the true running of the plate, is greatly facilitated, as it is merely necessary to true up in the lathe the contiguous faces of the shoulder and the offset.

In order that the purpose of the foregoingdescribed construction may be furtherv understood, I shall explain briefly'the parts with which the said plate is immediately connected.

At the rear end of the main frame of the machine is a cross-head, I), attached to the frame by bolts blrand having a cavity therein for the reception of the rear end of shaft A and the thrust-plates. This cavity also forms an oil-chamber, b5, Its rear sideis concave, to receive the convex rearward projection of a loose thrust-plate, b", which is prevented from turning by a vertical lug, b, that enters a groove in the rear of the box. By means of the nuts I) on bolts 0 adjusted longitudinally as occasion may require, and consequently the pugging-s'haft and its appendages, together with the thrust-plates as a whole.

Second. The next improvement relates to vthe'deta chable ribbed lining R, Sheet 3, of the screw-case S O; and it consists in adapting the same, so that it may be shifted around and secured so as to present a new surface underneath the expressing-screw S, Fig. 1, when the surfaccwhich has been in use has become worn away by reason of the friction and consequent wear from the attrition of the clay being obviously greater on the lower side. To accomplish this, I provide the rear edge of the saidmovable lining wit-hsuitable slots, r, for the reception of fastening-lugs N, which areseeured to the end of the screw-case by bolts 1", Figs. 8 and 9. \Vhen it is required to alterthe relative position of the lining, said bolts are unscrewed, when the lining may be rotated until the two other opppsite slots are brought into coincidence with the lugs 7-, re spectively, which are then'bolted in place.

the eross-head may be Third. The next improvement relates to the form of the lower end of the pipe M, through which the clay is delivered into t-he,tcmpcring-case, Figs. 1 and 19. The circle described by the free ends ofthe knives 7; being designedly usually four to six inches less in diameter than that of the innersidc of the case T C,

'there' is always left within the. latter a fixed shell or lining of clay. (Indicated by the brokenline circle at, Fig. 19.) Heretoforc this clay lining would gradually build itself up across the mouth of the inlet-pipe, and thus form an obstruction to the discharge of the clay into the case. This clay barrier had, therefore, to be broken away from time to time by meansof a pole thrust down the pipe. I now obviate this difliculty by extending the lower extremity of the latterdowninto the tempering-case, close to the sweep of the snbjaccnt knives,

and give to it the curvilinear form shown in Figs. 1 and lfl more clearly in the latter fig me. I have sometimes struck this curve upon the same radius as that of the circle made by the rotating knives; but I prefer to cut off the end of the pipe on the side first reached by the knives in their rotation, as shown in Fig. 19. The object of this preference is to prevent the breaking of the pipe by means of a large stone that, if the end of the pipe projected too far down on thatside, might be jammed against the latter by the knives. Besides, the lining of clay is-not apt to build itself up from that side.

By the constructiondescribed, it will be obvious that the clay lining is cut off from extending itselfup beyond-theproiccting curve'd end of the inlet-pipe, and thus aheretofore annoyance is escaped. I

Fourth. The next improvement consists in providing the die-case D Cwith laterallugs L on that side next to the pivoted eye or lock bolt 0, for the purpose of affording a suitable pur- ICC chase or fulcrum for a bar, 1 to aid in swinging open the die-case. (Seefigures on Sheet 3.)

That the nature of this improvement may be clearly apprehended, I shall explain that heretofore, owing to the elasticity of the clay packed in the screw and die cases, it was necessary, in order'tofree the eyebolt 0 before it could be swung out fromthe eye 0 of the diecase, preparatory to opening the latter, to unscrew the nut e" on the end of said bolt a considerable distance, and thereby considerable time was lost when it was required to open out the die-case in order to remove an obstruction lodged therein or for other purpose. insert the bar y,'Fig.-11,'bet\veen the upper oneof the lugs L and the end of the bolt e, first having slightly loosened the nut e", and by pressing against the barthe bolt is forced outward a certain distance. I then drop the Inow bar down between the bolt and the'lugsin the eye asufficient distance by the first operation described to allow this to bedone. I thenmanipulatethe bar against thefulcrunrlugs, and thus cause the boltto clear on'itshinge-h. V r The foregoing-described features relate; to

to the wire cutoff: mechanism and adjuncts described in my aforesaid application fora patent, whichwas filed on the 8th of February, 1883; and in order that these recent inrprovements may be fully understood and in their proper relations, I shall first explain the:

general construction andoperation of said cut-offmechanism. I Referring, primarily, drawings, the'clay that the die D to Fig.1 of the annexed is forced out through by the devices therein shown, or OHIGT'SllitfiblB' mechanism, is delivered P B, herein, and in said termed the propulsion-belt? This belt runs over pulleys P and l? and a series of rollers journaled in a horizontal f'aine, E. By reason of the friction of the advancing bar of clay' upon belt P B motion is imparted to the lat ter, which in turn sets in motion the cut-off devices, as will hereinafter appear. The cutoff mechanism consists of aseries of eguidis c w, stretched at distances apart equal to th'e'length of the bricks to be severed from-the clay bar upon'elastic U- 'shapedbows U, attached to-long flatplates D, in the manner upon an endlessbelt,,0 B, termed the cutoff belt, immediately over i and above-the path of the bar of clay. pulleys P and P, jo'urnaled in a verticallyadjustable frame, F, and they are arranged and adjusted, as shown, so that'the lever side of' the belt is'inclined towardfthe' propu lsionion,

give agood general idea of'the fo'r'the full comprehension of .the special improvements I am-about to describe.

Fifth. The firstof these (fifth-in the order of enumeration- Iliave adopted herein) relates 'to the vertical adjustment of that portion of the propulsion-belt frame Fto the rear of the vertical'ly-adjustable cut-off frame FL The object of such adjustment of fram'elF is it may be broughtto the proper height so as to insure the propulsion-belt being in line with I the bottom of the die of the machine-that is to of the bar of clay 1 say, in line with theunder side that asit'issues from the die. Iaccomplish this pur- -pose by means of vert cal screw-bolts.a, Fig.

porting legs a of the frame. I As the bolts are ,turned, sois the superincumbent frame raised or'lower'edi' As, owing to the flexibility of the bar of clay, K quired, it is unnecessary that theentlire beltirame should be moved, its end nextthe cutofi'jframe, and which end rests upon a. rear and the very little'adj ustmentsire projection, a", of the. latter,- is pivoted-on a I Si xth-.. Thenextimprovement to be described- .1s one of considerable importance to the suc- 'cessful operation of the cutoff under varying fer to'Figs. '1, l7, and 18; especially to the last figure. It isavell that I should first explain that'in'the machine which was thesubject ot' niy said allowed application for a patent the too ' conditions. In describing the same, Ishall re upward strain of the cut-off belt'occasioned by the resistance offered by the clay tothe passage through it of the cutoff wires was taken by closely together transversely in the inclined crosspieeesg of the cutoff frame 11",.as I

a. line'rof Small oller's J ournaled have termed it.. The defect in that construcf 'tion, as Isoon'discovered, was that the cut-off was marred, especially in very stony or gritty clays, by rea'sonof the trembling or wabbli'n of-the cut-off-wire supports and of the'cutofi belt, as there ,was o lateral orqunderneath support of the belt, or rather of the platesfD,

to which thewire-retaining U-shaped bows were secured. The present improvemefit is intended to, and does, in fact, remedy this defect. This-I do by making the pl ates D wider than vi ding, in lieu of the saidlinebf rollers ,-latera1 .guideways G on each side of the frame Ein the cross-pieces 9,, in which ways the side-extensions of th'eplates D beyond the edge of I toagreat-deg'ree, r

form the upper bearings of the plates D, by means of screws 9.

Seventh. Before entering upon a description of the important improvement now to be set forth, I shall explain that in the apparatus which was the subject of my said application filed February 8, 1883, I relied wholly upon the moving bar of clay, in connection with the propulsion-belt and the intermediate gearing, to propel the cut-off belt. I found, however, upon observing the operation of the devices with various kinds and consistencies of clay, that this was not reliable under all circumstances. VVhen the clay was in proper condition, it worked admirably; but when the clay became soft, and consequently issued from the die of .the machine with increased speed, and not havingsuffieient strength to propel the cut-off mechanism and cause itto respond to the acceleration, the bar would upset or buckle-up, and thus seriously interfere with the operation of the cut-off. In order to remedy this defect, I provide a device whose function isto conveya certain amount of power to the propulsion-belt, auxiliary to that of the sufficient to relieve the latter from doing more of the work of propel ling the cut-off mechanism than may, under any condition of the clay, be beyond its strength. In describing this device, which I shall term the compensator, I shall refer to the general elevation of the machine, Fig. 1, and to the enlarged detail, Fig. 18, Sheet 4., The shaft 8 of the forward propulsion-belt pulley, P, is extended beyond the frame in which it is journaled, andis provided with afiang'ed pulley, 1?, while a like extension of the shaft 8 of the bevel-gear by, Fig. 1, has in ling with pulley P a pulley, 1?", also preferably flanged on each side, (although not so shown,) so as to retain the slack friction-belt F B in place. This belt runs over both of said pulleys, and also over an idler-roller, I R, that is journaled at the forward end, L, of a lever, L L, which is ,secured to a stud, f pivoted to a bracket, f, of the post f", which supports the cut-off mechanism, &c. This lever bears on its other arm, L, a weight, .10, which is adjustable on the latter, and is held at any desired point by means of a thumb-screw, f

Referring to Fig. 1, the shaft 8 of pulley 1 "which shaft, I may state in passing, also carries the pulley 1"", Fig 1, that drives theoffbearing belt 0 B, is rotated from themain gearing of the machine through a shaft, 8, and

bevel gears b g and b g; and the relative diameters of the pulleys are .such' that the propulsion-belt may be driven at as great or greater speed than that at which the bar of clay may issue from the die, through the medium of the friction-belt connection. Now, it is manifest that as the pressure of the idler against the belt F B is increased or diminished, according to the position ofthe weight w upon the rear arm of the lever, a corresponding speed is lent to the propulsion-belt. The weight having been adjusted to suit the general character of the particular clay being worked, so that a suflicient compensatory power is conveyed to the belt P B for the purpose recited,

usually very little change in the adjustment is necessary.

I have referred to L L as a single lever, which it is in. effect. It is, however, preferably, though not essentially, a combination of two independent arms, oneof which, L, (see Figs. 13 and 14,) is keyed to the studf and the other, L, is rotatable thereon, and is secured in any desired position by a set-screw,

f The meaning of this construction is to provide anieans for keeping the arm L always in a horizontal position, while the idler may be adjusted up or down, so as to suit the length of the belt F B, which becomes slacker from use. I have also added a pulley, P P, Figs. 1 aiyd 13,'whichis journaled underneath the propulsion-belt frame adjacent to the pulley I", over which pulley P P the propulsionbelt is carried, whereby the latter is caused to hug the pulley I around some two-thirds ofits periphery, thus obviating the heretofore tendency of the belt to slip upon the latter.

'Eighth.

tic bows U are secured; and it consists in providing said plates at each end thereof with upturned flanges (1, Figs. 1,. 15, 1.7, and 18, between the margins of the plates which slide in the guideways G. These flanges serve also to stiffen the plates; but their principal purpose is to retain'the droppings of clay from the cut-off wires until the plates turn over the smaller pulley P, and which droppings might otherwise fall down upon the cut-off belt and get underneath plates D, thus preventing them from finding their proper bearing upon the surface of the belt.

Ninth. The next improvement has relation merely to the independent roller I, which, as before stated, receives upon it the end of the bar of clay; audit consists in giving the same The next improvement relates to the belt-plates D, to which the U-shaped elasrod a tapering form toward each end,as illustrated I This roller is struck by the cutin Fig. 16.

off wires suecesslvely as they, begin to turn up over the large pulley P, after having finally severed the bar of 'clay. Heretofore I have made the same quite cylindrical in form; but I discovered that the cut-off wires, owing to frequent bending over the roller and the sharply-defined or square edges thereof, would become weakened, and after a time break. By making-this roller tapering, as shown, it is adapted to the natural or even curve of the wires.

Tenth. The next improvement concerns the construction of the scraper S and its connections,which I use to clear the face of the cutoff-belt pulley P of any clay that may chance to drop upon and adhere to the same. The

'improvement consists in making the inclined wings H- (whose oifice is to deflect-the clay removed from the pulley by the scraper, so that bolt mayf be turned as-desired, merelyforcing it Will'fall'beyohd the machine) a fixed-part ofthe frame mounting the scraper thereon adjnstably, in:
